ANVlL-MOLD.

SFECIFIGATION forming part of Letters Patent No. 419,088, dated January7, 1890.

Application filed September 30, 1889. Serial No. 325,558. (No model.)

To all whom it may concern:

Be it known that I, THOMAS W. VARE, a citizen of the United States, andaresident of Trenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Improvements in Anvil-Molds; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Figure 1 of the drawings is a representation of a top view illustratingthis invention. Fig. 2 is a side view of the interior face of one of thelateral sections, showing the anvil. Fig. 3 is an end view partially insection, and Fig. i is a detail in perspective.

This invention has relation to improvements upon the anvil-mold forwhich Letters Patent No. 402,368 were granted to 1neApril30, 1889; andit consists in the novel construction and combination of parts, all ashereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letters A B designate the two lateralsections of the mold, which are preferably made of cast-iron, eachsection being recessed in its inner wall to provide one-half the matrix,as indicated at C. The sections A B are removably held together by meansof bolts C O, pivoted at their inner ends in the section A and let intogrooves or recesses C C in the two sections transversely of theirlengths, as shown in Figs. 1, 2, and 3.

D D are offset recesses extending laterally from the matrix-recesses atthe sides and middle portion thereof into the walls of the moldsections,as shown, and these offset recesses are designed to receive theslide-blocks E E, which are provided with the threaded turning-stems oroperating-screws F F, which engage the exterior threaded bearings G G.Each screw-stem is provided with a wrenchseat a at its end, whereby itmay be turned to cause the slide E to protrude into the matrix-cavityfrom the offset recess or to be withdrawn into the latter. \Vhen sowithdrawn, its end 6 is flush with the lateral wall of saidmatrix-recess. By means of these slides I am enabled, should the castanvil hang in either mold-section, to start it therefrom and easilyrelease it by turning the screw of the slide-block of that section tocause said block to move inward.

As described in the specification of my Letters Patent referred to, theanvil is designed to be cast base upward in the mold, and b and 0indicate the pouring-gates.

An openingI is made by means of horizontal squared notches or recessesin the rear of the mold-sections for the introduction of the face-platepiece K into the matrix. This openin g is made, preferably, in the rearof the mold, and its floor is level with the fioor L of the matrix. Theclosing-gate J for the opening extends transversely across the rear ofthe moldsections, and is held in place by a bar J, connected to one sideof the mold-section A and engaging a projecting end of the gate J.

j is a core at the inner edge of the gate J. It is provided with anupwardly-projecting flange f, beveled on its under side to form theunder bevel of the rear of the anvil. Below this bevel-flange isprovided a transverse recess, as at g, to receive a fender-piece of sandor clay composition, (indicated at h,) and designed to prevent thecasting from being chilled in the corners by the iron of the mold. Inorder to allow a small portion of the iron which first passes into themold, which is usually of inferior nature, to escape, the mold isprovided with a waste-aperture at o below the gate, which is notched ato. The clay binder is also notched to allow the metal to pass out. Aftera sufficient quantity has escaped a clay plug is used to stop theopening.

At the lower corner portions of the matrix, extending the length of thesame,ofiset channels Z are made in the mold-sections, said channelsbeing preferably angular in form and extending a short distance from thebottom of the matrix up the sides thereof and a short distance inwardalong the bottom from each side, as shown. These recesses or seats aredesigned to receive the longitudinal clay fender-pieces h, to preventchilling at the edges of the joining of the casting to the faceplatepiece K by the cold metal of the mold. The steel face-plate piece K, asWell as the hornplate', is placed in the bottom of the matrix before thecast-iron is poured into the mold, and it is designed by this mold toefi ect an intimate joining of the steel plates to the cast iron body.To this end the face-plate is ground bright and clean to remove all theblack,which Would interfere with the Welding side, to provide thinprojections of the steel, which,when the iron is poured into the mold,are easily softened or melted to form a speedy and intimate union withthe cast-iron. In this manner the main portion of the Welding is madeVery solid, and in order to prevent chilling at the edges of the Weldingthe clay fenders are provided in the angles of the mold.

Having described this invention, What I claim, and desire to secure byLetters Patent, is-

1. A sectional metallic anvil-mold having steel face-pieces in thematrix and clay fillin gs in offset recesses at the angles of thevertical Walls of the matrix with the floor to prevent chilling inWelding.

2. In a sectional metallic anvil-mold, the combination, with themold-sections, the jagged steel face-piece, the matrix, and the recessesin the Walls at the angles of the matrix, of the clay fillings in saidrecesses, substantially as specified.

3. In a sectional metallic anvil-mold, the Waste-opening to allow theescape of the first portion of the melted metal. in combination with thenotched gate, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

THOMAS W. VARE.
